How to Remove and Install a Car Alternator: A Comprehensive Guide

“Just like the old saying goes, ‘A stitch in time saves nine,’ the same applies to trucks. To ensure longevity, you need to know how to care for them.” My friend, the owner of a Dongfeng B180 truck used for transporting construction materials on Nguyen Trai Street, Ha Dong, shared this wisdom. That day, he was wrestling with his alternator, which seemed to be malfunctioning. He explained that the alternator is the “heart” of the vehicle, powering all its electrical operations, and a weak “heart” hinders the truck’s performance. Seeing him struggle alone, I thought, why not write a comprehensive guide on removing and installing a car alternator to help those in need?
